'Application filed February 17 1927. Serial 110.169,104.

Thisinvention relates to twisting` implements and more particularly to hand implements, although certain features thereof may be used. with equal advantage for other purposes.

- 1t contemplates more especially the provision of wire tie means capable of rotation `responsive to intermittent oscillations iinparted thereto whereby an article may be conveniently and eectively applied or removed as desired.

. Wire ties have longbeen employed to bind articles together; however, much difficulty has been encountered in tensioning the ties so as to effect a rigid joinder of two or more members otherwise separable.

One object of the present invention is to simplify the construction and improve the operation of devices of the character mentioned. v

`Another lobject is to provide an implement capable of freely receiving an object therein, to effect the application or removal thereof.

A further obje-ct is to provide a ratchet implement capable of receiving an object therein in a predetermined position only.

Other objects and advantages will appear from the following description of an illustrated embodiment of the present invention.

In the drawings:

Figure 1 is a plan view of a device embodying features of the present invention.

Figure 2 is a view in elevation of the device shown in Figure 1.

Figure 3 is a sectional view taken substantially along line II-III of Figure 2.

Figure 4t is a fragmentary view, with parts omitted, of the device shown in Figure 3, with the head thereof disposed in a different position.

Figure 5 is a sectional view taken substantially along line V-V of Figure 1.

Figure 6 is ajview showing one application of the device in tensioning a wire tie about an I-beam and plate disposed therebelow.

Figure 7 is a sectional view taken substantially along line VII-V11 of Figure 6.

The structure selected for illustration comprises a handle 10, in this instance composed of a pair of parallel spaced plates 11 and 12 stamped or otherwise formed to define a shank portion 13 having a substantially circular head 14tdefining a circular raceway 15 partially open as at 16. The plates 11 and 12 are maintained in spaced relation by means of the tubular members 17 which receive therey through the screws 17', in this instance two, projecting through the handles and spacer elements 16, thereby securing them together to provide a unitary' handle 10. i

A revoluble member 18 having a projecting circumferential portion 19 formed interme- .diate the ends thereof, is journalled in the raceway 15 so that the projecting portion 19 is disposed between the plates 11 and 12. As shown, the projecting portion 19 is provided with a' plurality of-u'niformly spaced ratchet A teeth 20 on the periphery thereof tocooperate with a pawl 21pivotally associated with the handle 10 intermediate the plates 11 and 112 near the head thereof, it being provided with a slot 22 which receives a pin 23 fixed to the handle 10,'to render the pau/121 pivotally and slidably adjustable into and lout of engagement with the ratchet teeth 20. Y

Resilient means, in this instance a fiat yieldable spring 24, is anchored to the spacing element 16 which is in proximity to the head 14 ofthe handle 10, in any appropriate manner, suchas by projecting the bent extremity 25 thereof into a cooperating recess 26, the spring 211 being maintained in engagement with the pawl 21 by disposing the former between two pins 27 and 28 which are spaced to cause the free extremity ofv the spring to normally urge the pawl in operative engagement with the revoluble member 18. With the arrangement of parts thus far described,

it will be apparent that oscillatory movement of the handle 10 will impart rotation to the revoluble member 18 in an obvious and wel] known manner.

In order to enable an article to be received by therevoluble member 18 through'the opening 16 in the handle head 14, the member 18 is provided with suitable grooves, in this instance two, 29 and 30, which are spaced from -f each other tovdefine an 'intermediate projecting member 31 constituting in ythis instance one of the ratchet teeth 20, as will hereinafter appear. The grooves 29 and 30, in this instance, extend inwardly for a distance slightly beyond the center of the member 18 and terminate outwardlyto define an interrupted periphery without destroying the continuity `of the uniformly spaced teeth 2() which are with the opening 16 in the head 14 of the handle 10 when the former is in al predetermined position to freely receive an object therein for imparting rotary movement thereto.

In the present embodiment the grooves are so formed as to receive therein spaced tie Wires 32 which can be effectively twisted t0 tension them about objects as will be apparent from the showing in Figures 6 and 7. To insure the retention of the wires or other 0bjects received within the ratchet member 18, a. guard is provided. The guard, in this instance, comprises a substantially arcuate plate 33 shaped to conform with the head 14, it being provided with a correspondingly shaped groove 34 extending for the major length thereof to receive the screws 35 secured to one of the handle plates whereby the guard 33 is slidably mounted thereon to permit it to selectively bridge the open end 16 of the head 14 when shifted from its retracted position. v i

' It will be apparent from the above that a novel implement has been provided which is efective to impart rotary movement to an article responsive to oscillations manually or otherwise applied to the implement, in this instance to the handle 10.

I am aware that many changes may be made, and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim as my invention:

1. In a device of the character described, a handle having an open circular raceway therein, a revoluble member journaled therein, said revoluble member having an interrupted periphery with ratchet teeth spaced uniformly thereon, and a spring controlled pawl having a slot therein and pinned to said handle through said slot to normally cooperate with said ratchet teeth, said pawl having a plurality of teeth in operative engagement with the ratchet teeth on said rovoluble member.

2.V In a device of the class described, a han.'- dle comprising a pair of platesl secured together in spaced relationship, an enlarged head portion on said handle havin a raceway therein., a rotatable ratchetv mem erjournaled in said raceway and extending between f said plates, said ratchet yhaving apair of inlwardly extending grooves therein, a `multitoothed pawl resiliently controlled and pivotally mounted on said handle vbetween said plates, and an arcuate member slidably mounted onone of said plates to selectively close the entrance to `said raceway.

In'testimony whereof I have hereunto subscribed my name.
